Who Puts The "Support" In Supportive Housing? The Impact Of Housing Staff On Resident's Well-Being, And The Potential Moderating Role Of Self-Determination, Kenna Estell Dickard

Dissertations and Theses

The provision of residential and community-based services for individuals with serious mental illness (SMI) has become increasingly important following the deinstitutionalization movement. Much of the existing research on supportive housing focuses on housing outcomes rather than exploring how the program helps its residents thrive in the broader community. This study draws upon data collected from 176 people with SMI residing in 16 supportive housing locations in Portland, Oregon. Analyses employed an ecological approach, exploring how housing staff support relates to residents' well-being at three levels of analysis: loneliness (interpersonal level), residential satisfaction (housing and neighborhood level), and sense of community …

Asymptotics And Sign Patterns For Coefficients In Expansions Of Habiro Elements, Ankush Goswami, Abhash Kumar Jha, Byungchan Kim, Robert Osburn

School of Mathematical & Statistical Sciences Faculty Publications

We prove asymptotics and study sign patterns for coefficients in expansions of elements in the Habiro ring which satisfy a strange identity. As an application, we prove asymptotics and discuss positivity for the generalized Fishburn numbers which arise from the Kontsevich–Zagier series associated to the colored Jones polynomial for a family of torus knots. This extends Zagier’s result on asymptotics for the Fishburn numbers.

The Role Of Metallothioneins In Copper Homeostasis In Arabidopsis, Matthew Vandal

LSU Doctoral Dissertations

Copper (Cu) is a transition metal that is an essential nutrient for plants and is required for a number of critical processes. Therefore, proper homeostasis of copper is vital for plant life and must be tightly regulated. Metallothioneins are small molecular weight proteins, rich in cysteine residues and have the capability of binding to several different transition metals such as copper. Cu induces the expression of MTs, therefore they are believed to be involved in Cu transport, however their true functions have yet to be resolved. T-DNA insertions were identified in four Arabidopsis MT genes expressed in vegetative tissues, and …

What Happens Online Doesn't Stay Online: Female Elected Officials' Experiences With Online Harassment, Sarah M. Carpenter

LSU Doctoral Dissertations

Online harassment towards female elected officials is a prevalent problem that threatens women’s parity in local and state government. It is used for the purpose of diminishing women’s efficacy in government by stifling their voices in public spaces through behaviors that aim to belittle, embarrass and abuse women for existing in traditional masculine spaces that reify a white patriarchal social hierarchy. Female elected officials at all levels of government are susceptible to harassment on- and offline. The aim of this study expands current understandings of how online harassment affects female elected officials by focusing on online harassment experiences of women …

“Why We Play The Game”: An Exploration Of Sport Employees’ Conceptualizations Of Meaningful Work, Nathan Baer

LSU Doctoral Dissertations

Modern sport management scholars have looked to pair the fields of positive organizational behavior (POB) and human resource development (HRD) with sport management to enhance the productivity of sport organizations through their employees (see Kim et al., 2019; Kim et al., 2023a; Kim et al., 2023b; Kim et al., 2017; Oja et al., 2015, 2020; Oja et al., 2022; Schuetz et al., 2022; Zvosec et al., 2021). One area of study that has received recent attention amongst sport management scholars is meaningful work (Baer et al., 2021; Oja et al., 2022), an emerging employee well-being metric whose definition is often …

Sportsman's Paradox: Conservationism And Social Progress In Modern Louisiana, Jacob T. Gautreaux

LSU Doctoral Dissertations

Over the nineteenth and early twentieth centuries, sportsmen increasingly identified Louisiana as a destined paradise due to the abundant flora and fauna. Confirmed in the legendary visits of Theodore Roosevelt in the early 1900s, the conception soon served a dual purpose as individuals like the Tabasco Sauce patriarch, E. A. McIlhenny, coopted the visualization as a lure for business investment into the nascent industrial interests within the coastal region of the state. However, it should be noted that in the 1930s and beyond, cultural conservationists like McIlhenny and Caroline Dormon preserved elements of under-documented cultures throughout the state, although usually …

Advancements In Middle School Agricultural Education: An Examination Of Emerging Trends And Exemplary Programs, Jacob P. Englin

LSU Master's Theses

Recent trends in agricultural education have demonstrated that the number of middle school programs and students has been increasing. Despite this, middle school agricultural education students, teachers, and programs often have been considered to be underserved. For example, teachers at this level have expressed that they often lacked the training and resources to meet the needs of this diverse learning population. Even so, middle school agricultural education teachers have continued to provide quality learning experiences for their students. In response, this investigation’s purpose was to examine current trends of middle school agricultural education and the quality of learning conducted by …

Reef Fish Movement Dynamics And Recruitment To Artificial Habitat, Jade Carver

LSU Master's Theses

Artificial reefs provide critical habitat for fish in areas lacking benthic structure, yet our understanding of how artificial reefs function and develop is limited. Here, changes in reef fish community assemblages were monitored using baited remote underwater video (BRUV) surveys (n=6) before and after a new artificial reef was deployed. Movement of red snapper (Lutjanus campechanus, n=20) and gray snapper (Lutjanus griseus, n=20) between nearby platforms (n=3) and the new artificial reef was examined using acoustic telemetry, and residency was calculated for fish associated with platforms and the artificial reef …

Development And Testing Of A Mapcheck3-Based Patient-Specific Qa Method For Prime Intensity Modulators Used With Bolus Electron Conformal Therapy, James T. Crist

LSU Master's Theses

Purpose: Irregular surfaces in bolus electron conformal therapy (BECT) create target volume dose inhomogeneity, which off-axis intensity modulation (IM) can reduce. This research developed and tested a patient-specific clinical quality assurance (QA) procedure for fabricated Passive Radiotherapy Intensity Modulation for Electrons (PRIME) devices used for IM-BECT delivery.

Methods: To evaluate MapCheck3 (MC3) diode array accuracy, electron dose measurements beneath PRIME devices were compared with scanned measurements in a water phantom. Lateral dose profile comparisons were made for 35 combinations of five beam energies (7-20MeV) and seven PRIME devices - converging and diverging island blocks (pins) having 100-68.8% intensities. To evaluate …

Distribution Of Carbon Dioxide Emissions And Potential Consequences For Their Reduction In Louisiana, Mumtahinah Zia

LSU Master's Theses

As a part of a global concern, the United States is targeting to reach carbon dioxide (CO2) reduction goals along with other countries. However, to better understand optimal strategies of reducing CO2 emissions, given the diversity of the resource and economic base of regions in the United States, an understanding is needed of how the components that make up total final demand including households, industries and trade contribute to the overall well-being for these regions, specifically at the state level. Moreover, there are strategies that assist in meeting CO2 reduction policy targets. In this thesis, I have addressed these issues …

Propensity Score Analysis With Local Balance, Yan Li, Liang Li

Faculty, Staff and Student Publications

Most propensity score (PS) analysis methods rely on a correctly specified parametric PS model, which may result in biased estimation of the average treatment effect (ATE) when the model is misspecified. More flexible nonparametric models for treatment assignment alleviate this issue, but they do not always guarantee covariate balance. Methods that force balance in the means of covariates and their transformations between the treatment groups, termed global balance in this article, do not always lead to unbiased estimation of ATE. Their estimated propensity scores only ensure global balance but not the balancing property, which is defined as the conditional independence …

Accumulation Of Chronic Disease Among Survivors Of Childhood Cancer Predicts Early Mortality, Adam J Esbenshade, Lu Lu, Debra L Friedman, Kevin C Oeffinger, Gregory T Armstrong, Joseph P Neglia, Rebecca Howell, Robyn Partin, Amy Sketch, Leslie L Robison, Kirsten K Ness

Faculty, Staff and Student Publications

Purpose: Cancer survivors develop cancer and treatment-related morbidities at younger than normal ages and are at risk for early mortality, suggestive of an aging phenotype. The Cumulative Illness Rating Scale for Geriatrics (CIRS-G) is specifically designed to describe the accumulation of comorbidities over time with estimates of severity such as total score (TS) which is a sum of possible conditions weighted by severity. These severity scores can then be used to predict future mortality.

Methods: CIRS-G scores were calculated in cancer survivors and their siblings from Childhood Cancer Survivor Study cohort members from two time points 19 years apart and …

Effect Of Reduced Versus Usual Lipid Emulsion Dosing On Bilirubin Neurotoxicity And Neurodevelopmental Impairment In Extremely Preterm Infants: Study Protocol For A Randomized Controlled Trial, Eric W Reynolds, Andrew H Huber, Matthew A Rysavy, Maria Del Mar Romero Lopez, Amir M Khan

Faculty, Staff and Student Publications

BACKGROUND: Bilirubin neurotoxicity (BN) occurs in premature infants at lower total serum bilirubin levels than term infants and causes neurodevelopmental impairment. Usual dose lipid infusions in preterm infants may increase free fatty acids sufficiently to cause bilirubin displacement from albumin, increasing passage of unbound bilirubin (UB) into the brain leading to BN and neurodevelopmental impairment not reliably identifiable in infancy. These risks may be influenced by whether cycled or continuous phototherapy is used to control bilirubin levels.

OBJECTIVE: To assess differences in wave V latency measured by brainstem auditory evoked responses (BAER) at 34-36 weeks gestational age in infants born …

Mct4-Dependent Lactate Secretion Suppresses Antitumor Immunity In Lkb1-Deficient Lung Adenocarcinoma, Yu Qian, Ana Galan-Cobo, Irene Guijarro, Minghao Dang, David Molkentine, Fahao Zhang, Jing Wang, Edwin Parra, Apekshya Panda, Jacy Fang, Ferdinandos Skoulidis, Ignacio I Wistuba, Svena Verma, Taha Merghoub, Jedd D Wolchok, Kwok-Kin Wong, Ralph J Deberardinis, John D Minna, Natalie I Vokes, Catherine B Meador, Justin F Gainor, Linghua Wang, Alexandre Reuben, John V Heymach

Faculty, Staff and Student Publications

Inactivating STK11/LKB1 mutations are genomic drivers of primary resistance to immunotherapy in KRAS-mutated lung adenocarcinoma (LUAD), although the underlying mechanisms remain unelucidated. We find that LKB1 loss results in enhanced lactate production and secretion via the MCT4 transporter. Single-cell RNA profiling of murine models indicates that LKB1-deficient tumors have increased M2 macrophage polarization and hypofunctional T cells, effects that could be recapitulated by the addition of exogenous lactate and abrogated by MCT4 knockdown or therapeutic blockade of the lactate receptor GPR81 expressed on immune cells. Furthermore, MCT4 knockout reverses the resistance to PD-1 blockade induced by LKB1 loss in syngeneic …

Glucose-Enhanced Oxidative Stress Resistance—A Protective Anticipatory Response That Enhances The Fitness Of Candida Albicans During Systemic Infection, De Larcombe, Im Bohovych, A Pradhan, Q Ma, E Hickey, I Leaves, G Cameron, Gm Avelar, Lj De Assis, Ds Childers, Jm Bain, K Lagree, Ap Mitchell, Mg Netea, Lp Erwig, Nar Gow, Ajp Brown

Peninsula Medical School

Most microbes have developed responses that protect them against stresses relevant to their niches. Some that inhabit reasonably predictable environments have evolved anticipatory responses that protect against impending stresses that are likely to be encountered in their niches–termed “adaptive prediction”. Unlike yeasts such as Saccharomyces cerevisiae, Kluyveromyces lactis and Yarrowia lipolytica and other pathogenic Candida species we examined, the major fungal pathogen of humans, Candida albicans, activates an oxidative stress response following exposure to physiological glucose levels before an oxidative stress is even encountered. Why? Using competition assays with isogenic barcoded strains, we show that “glucose-enhanced oxidative stress resistance” phenotype …

Roving Methyltransferases Generate A Mosaic Epigenetic Landscape And Influence Evolution In Bacteroides Fragilis Group, Jung-Ho Youn, Pavel P Khil, John P Dekker

Faculty, Staff and Students Publications

Three types of DNA methyl modifications have been detected in bacterial genomes, and mechanistic studies have demonstrated roles for DNA methylation in physiological functions ranging from phage defense to transcriptional control of virulence and host-pathogen interactions. Despite the ubiquity of methyltransferases and the immense variety of possible methylation patterns, epigenomic diversity remains unexplored for most bacterial species. Members of the Bacteroides fragilis group (BFG) reside in the human gastrointestinal tract as key players in symbiotic communities but also can establish anaerobic infections that are increasingly multi-drug resistant. In this work, we utilize long-read sequencing technologies to perform pangenomic (n = …

2020-Current year OA Pubs

Real-time surveillance of airborne SARS-CoV-2 virus is a technological gap that has eluded the scientific community since the beginning of the COVID-19 pandemic. Offline air sampling techniques for SARS-CoV-2 detection suffer from longer turnaround times and require skilled labor. Here, we present a proof-of-concept pathogen Air Quality (pAQ) monitor for real-time (5 min time resolution) direct detection of SARS-CoV-2 aerosols. The system synergistically integrates a high flow (~1000 lpm) wet cyclone air sampler and a nanobody-based ultrasensitive micro-immunoelectrode biosensor. The wet cyclone showed comparable or better virus sampling performance than commercially available samplers. Laboratory experiments demonstrate a device sensitivity of …

Probabilistic Modeling Of North Atlantic Ocean Hurricane Spawn Considering Climate Change, Susmita Bhowmik, Weichiang Pang, Michael Stoner

Publications

Hurricanes are a significant natural hazard, which cause significant damage and financial losses in the coastal areas of the United States almost every year. For example, the devastating nature of North Atlantic Ocean (NAO) storms can easily be understood from the 2005 Hurricane Katrina, which was the most damaging NAO storm in modern history, causing more than 1,800 deaths and a financial loss of at least 161.3 billion USD. It has been found that the formations of hurricanes depend heavily on climate conditions, which implies a direct relationship between the changes in climate extremes and the occurrences of hurricanes or …

(Dis)Locating Meaning: Toward A Hermeneutical Response In Education To Religiously Inspired Extremism, Farid Panjwani

Institute for Educational Development, Karachi

A key epistemological assumption in the ideologies of many of the groups termed extremist is that there is an unmediated access to a Divine Will. Driven by this assumption, and facilitated by several other factors, a range of coercive actions (including violence) to force others into submission to the perceived Will of God are seen as justified by some of these groups. A consideration of how religion is discussed in various contexts, from seminaries and schools to media and policy discourses, shows that this assumption about unmediated access to Divine Will is widely shared and that most children grow up …

Efficient Super-Resolution Of Near-Surface Climate Modeling Using The Fourier Neural Operator, Peishi Jiang, Zhao Yang, Jiali Wang, Chenfu Huang, Pengfei Xue, T. C. Chakraborty, Xingyuan Chen, Yun Qian

Michigan Tech Publications, Part 1

Downscaling methods are critical in efficiently generating high-resolution atmospheric data. However, state-of-the-art statistical or dynamical downscaling techniques either suffer from the high computational cost of running a physical model or require high-resolution data to develop a downscaling tool. Here, we demonstrate a recently proposed zero-shot super-resolution method, the Fourier neural operator (FNO), to efficiently perform downscaling without the need for high-resolution data. Because the FNO learns dynamics in Fourier space, FNO is a resolution-invariant emulator; it can be trained at a coarse resolution and produces emulation at any high resolution. We applied FNO to downscale a 4-km resolution Weather Research …

Evaluation Of Salvinia Weevil Establishment, Dispersal, And Environmental Pressures Impacting The Giant Salvinia Biological Control Program, Korey Danielle Pham

LSU Master's Theses

Giant salvinia (Salvinia molesta Mitchell), an invasive free-floating aquatic fern, invaded the Toledo-Bend reservoir along the Texas-Louisiana border in the 1990s. The rapid spread threatens critical ecosystems, economies, and cultural services by altering water quality, and impacting fishing, hunting, and navigation. To combat this issue, the LSU AgCenter has been rearing and distributing the salvinia weevil (Cyrtobagous salviniae Calder and Sands), which has demonstrated effectiveness in reducing giant salvinia populations within a matter of months to a few years. The first study assessed the impact of propagule pressure on salvinia weevil effectiveness in outdoor mesocosms and revealed that …
